Can I use sub_id and set it to cid in dnxhd decoder ?

Also, avid codecs need those specific mov atoms for some codecs ffmpeg
already supports, what would be the good way to write them ?

Example: you can mux dv into mov using "AVdv" tag, then avid codecs will
decode stream perfectly if those atoms are present, though quicktime
wont decode it by default.

Quicktime has a native decoder for dv25 so use native one, but for dv50,
  there is no decoder. We can use Final cut one, which use his own
codec/own tag but only useable when fcp is installed, or Avid ones which
are freely available.

So what muxing by default, and how to switch ? codec_tag ("stsd" tag) is
a solution, but people will have to know which tag to use.
